VirtualBox Result code E_FAIL 0x80004005? Easy Fixes

VirtualBox Result code E_FAIL 0x80004005?: The VirtualBox Result code E_FAIL (0x80004005) Fails to begin, displaying an error message. Memory leaks may affect Visual Studio’s performance. Regardless, further issues may cause E_FAIL (0x80004005). Such as non-failure of virtualization in BIOS, outdated virtual box, memory integrity features interfering with the process, etc. Fortunately, some solutions will help you solve your problems. Use all the solutions individually and solve the virtual box error without wasting time.

How to Resolve VirtualBox Result code E_FAIL 0x80004005

Solution 1: Restart and disable Hyper-V via Command Prompt

Starting with version 6.0, VirtualBox supports the Hyper-V API and allows it to run with Hyper-V. If you use an out-of-date version of VirtualBox, it will not be compatible with Windows Hyper-V. HyperV prevents virtual machine startup. Rebooting the hypervisor will reset the system and clean up any corrupted files created by the mistake. It can help clear up any memory issues which cause hardware-related issues with errors.

Follow the instructions below to restart the hypervisor:

  • Type cmd in the search box.
  • Right-clicking on Command Prompt and choose Run Administration. Type the below command in the command prompt and press Enter key.
  • bcdedit /set hypervisor launch type off

  • Restart your system to verify the problem is resolved. If not, activate Hyper-V.
  • Launch the command prompt.
  • Type your next command.
  • bcdedit /set hypervisor launch type auto
  • Restart the system and restart the virtual machine.

Solution 2: Check the VM XML File

If you encounter an e-file error, Find two files in the “C:UsersCOMPUTER_NAME..VirtualBoxMachinesVM_NAME” directory.

  • VM_NAME.xml-prev
  • VM_NAME.xml-tmp

VirtualBox requires an XML file to start the VM. But the “VM_NAME.xml” file is absent when an error is thrown. To solve this problem, copy the File first and rename it “VM_NAME.xml-prev.” Once it’s done, restart Virtualbox, and your error will be fixed.

Solution 3: Install VBoxDrv.inf Manually

The driver VBoxDrv.inf is required for VirtualBox. It may not install correctly owing to permissions. It prevents virtual machine startup. The resulting virtual box code will be E_FAIL (0x80004005). VBoxDrv.inf must be manually installed to resolve this.

  • Locate the inf file in the VirtualBox installation folder (by default, C: Program FilesOracleVirtualBoxdriversvboxdrv).
  • Right-click the File and pick the Install option.

Solution 4: Disable Hypervision Processes

Running VMs with HyperV enabled is not allowed with VirtualBox 5. X. Hyper-V requires specific virtualization resources, which VirtualBox does not provide. Fixing the issues requires turning off all Hyper-V.

Follow these instructions to disable HyperVersion on the system:

  • To launch the Turn Windows Features on or off the wizard, use Windows + I to visit Settings > Apps > Optional Features.
  • Find the options below and uncheck them.
  • Hyper-V,
  • Containers,
  • Windows Hypervisor Platform,
  • Windows Subsystem for Linux.

  • Close the wizard and launch the Command Prompt as an administrator.
  • In the Command Prompt, run bcdedit /set hypervisor launch type off and hit Enter.
  • Reboot the computer and see if the result code E_FAIL (0x80004005) is fixed; if not, move on to the following step.

Solution 5: Disable Device Guard or Credential Guard

Device Cards and Credential Guards use virtualization technology to protect computers and credentials from external threats. By enabling these features, virtualization issues will be reduced, and errors may occur. Follow the steps below:

  • Click the Windows icon and enter CMD into the search box.
  • Now, right-click the command prompt and pick Run as administrator.

  • Launch the command with administrative privileges and enter the following instructions.

mountvol X: /s

  • copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y
  • bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d “DebugTool”/application osloader
  • bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path “\EFI\Microsoft\Boot\SecConfig.efi”
  • bcdedit /set {bootmgr} boot sequence {0cb3b571-2f2e-4343-a879-d86a476d7215}
  • bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} load options DISABLE-LSA-ISO mountvol X: /d
  • [NOTE: In the above command, replace X with your unused drive.]

Solution 6: Disable Memory Integrity

Memory Integrity uses virtualization to isolate activities to protect the underlying system from external threats. Try disabling memory integrity to see if that fixes the e_fail (0x80004005) problem.

Follow these steps:

  • Sign in as an administrator to your computer system, click Windows Key on your PC, and type window security in the search box. Next, Open it.
  • In the left pane, go to the Device Security tab.
  • Following that, choose the Core isolation information menu as shown.
